Question

a certain mass of Nitrogen gas at 20°C and at 740 pressure occupies 12.345 dm³. calculate the volume that it will occupy at STP​

Answer 1

Explanation:

Number of moles of nitrogen = 7/28=1/4 moles

As we know, one mole occupies 22.4 litre volume.

Therefore, 1/4 mole will occupy, V= 22.4/4

=5.6 litre

Answer 2

A certain mass of Nitrogen gas at 20°C and at 740 pressure occupies 12.345 dm³. calculate the volume that it will occupy at STP

At STP , P1 = 760

V1 = ?

T1 = 273

P2 = 740

V2 = 12.342

T2 = 293

________________________

P1 V1 / T1 = P2 V2 / T2 [ PUTT THE VALUE IN THIS FORMULA ]

The answer is 11.19 dm ³

_____________________________

V = volume

P = pressure

T = temperature
